To ALL- WHOM 1T- MAY CONCERN:

Be it known that I, J. W. KELLEY, of Cleveland, in the county of Culahoga, and State of Ohio, have invented certain new and useful Improvements in Whittie-Tree; and I do hereby declare that the following is a. full and complete description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1.- is a. side view.

Figure 2, a. detached view..of the cross-bnr.

Figure 3, a. detached view of whiiieJx-ee.

Figure 4, detached plates.

Like letters ofj reference refer to like parts in the views.

In fig. 1, A represents the whiiiie-tree, and the cross-bar, to which it is attached. C is a metallic plete, in the face of whichare formed dove-tailed segmental grooves, D, seid segments having a common centre-pin, B. `Corresponding to these grooves are arranged on the plate Ffdove-tailed segmental ribs, G, having a. common centre or hole, H, for the admissionA of -the pin B'. p

These ribs are made to lit and work freely in the grooves D on the two plates, being brought together for the purpose of coupling thewhiiie-tree tothe cross-bar. v i

Either of said plates is secured to the\under side of the 4Whittie-tree, as shown` in iig. B, and lto the upper side of the cross-har. Thetwo are then placed together, es shown in iig. 1, in whiich it will be seen that the rib is enclosed by the groove, and in which it freely slides on turning the whie-tree, and at the same time attaching the. whiie-tree to-the'ba'r in a neat, secure, :md permanent manner.

The-usual manner of oupling'the V\vhifile-t1'ee tothe bar is by inserting a bolt through them, said bolt forming a pivot, on which the Whittletree swings.

. For greater security, a. stay or clamp is made to embrace the tree and bar from behind, and through the ends of which the boit is inserted. y

This manner of couplin'gis` not only expensive but insecure, as the nut on the bolt referred to often works o6', and said' bolt, in consequence, is liable to dropout. v Butwherr the eoupling'is made in lthe manner its above described, no bolt or stay is required, as the rib and groove secure the whili'le-tree in the bor, net only with greater safety, but et a much less expense. Ilz-is elso neeter in appearance, and the tree can be put on or taken 'off much easier and in vless time than one coupled with a. bolt und clamp in the ordinary way.

What lI claim as my improvemenhvaud desire to secureby Letters l)atent, is The dove-tailed groove-plete C, in combination with the dove-tailed ribbed plate F, in the manner as and for the purpose set forth. Y i
